Designed for HiLook/Hikvision cameras with 120mm base, e.g. PTZ-C4MP or any other with the mount plate as on the picture below.

The mount has a hole for Ethernet cable and is mounted to the camera with 4 screws.

Provided STL has no holes to attach the mount to the ceiling as I used strong 3M tape. Holes can easily be added by just using a drill or by editing F3D file.
